MS-NAP posture check shows "Not-Capable" on Clearpass

Hello,

First time poster. I am relatively new to Clearpass and Aruba products in general, so forgive me if I have overlooked something obvious. I wasn't able to find an answer within the documentation or forums.

I am attempting to configure a Clearpass posture check using the built-in MS-NAP agent in Windows. My client is running Windows 7 SP1, and I have started the NAP service on the client. However, when I attempt to authenticate, I am still met with a posture token of UNKNOWN, and if I dig into the Computed Attributes, I see that "Authentication:Posture" reads "Not-Capable" (see attached image). I even went to double verify that the NAP agent is running, so I'm not sure what else needs to be done. Is there additional configuration that needs to also be done on Active Directory? I figured Clearpass took the place of Windows Server as the NAP "authenticator" or what have you, so I didn't think anything else is needed on that end.
